A lot of good suggestions already here. Try to eliminate the mosquitoes in your house as much as possible. I installed mosquito nets on my windows a few years ago. This helped a lot. I am now asking myself why I haven’t done this before.

But I do still get bites like one or two a day, because I also like to be outside in my garden and sometimes a mosquito still finds a way into the house.

So there is no way you can prevent all bites. But the good thing is, you can treat them really well really easy with heat! I do this when I have a cup of tea. I just press the hot tea cup on the bite for a short while. But there are also special pen like devices called electronic insect bite healer or something similar. They are about 10-20 euros. They work as well and are probably safer and easier to handle.

Heat does disintegrate the anticoagulant that mosquitos inject and that makes the bites so itchy. The bites I get itch only ones. Then I treat them with heat and they are basically gone. Try to not scratch because you might spread the anticoagulant more. Just treat them right away!
